The trouble is that AbsL parts of the test are arch-specific, as only {x86_64,aarch64,ppc64,s390}.ad have the match rules for AbsL. x86_32.ad does not have it, so C2 never actually emits AbsL in x86_32 case. AbsI, AbsF, AbsD are also not supported by arm.ad. I wonder if IR Test Framework might be able to disable subtests based on arch... It is probably all around easier to make this test x86_64 specific. It tests shared C2 code, so testing one architecture is probably enough.
